Screen readers use WAI-ARIA roles to determine what kind of content a layout holds. In Pega Platform, screen layouts have WAI-ARIA roles assigned by default, which improves the accessibility of your application.
The following table lists the areas in a screen layout, the corresponding auto-generated HTML tags, and the WAI-ARIA roles that are assigned to those areas by default.
For more information on screen layouts, see Configuring a screen layout.
|Area position||Auto-generated tag||WAI-ARIA role||Notes|
|Header||<header>||banner||Empty in theme Cosmos|
|Navigation||<aside>||complementary||Not consistent with WAI guidelines|
|Aside||<div>||none||Not consistent with WAI guidelines|
